I agree - interesting discussion.
How do non-addicts experience pleasure from alcohol? They are having pleasure, not their beasts, yes?
IF that is the case (lots of room for discussion on that topic, I think), then I would also be capable of having a pleasant sensation from alcohol, not only my beast.
It's a moot point, since my beast's pleasure is so overwhelming I'd never be able to differentiate it during a drinking experience (or recall it). I just think it's probably still in there. The beast is additive, often overwhelming, to my normal (non-addict) brain experiences. It doesn't have the power to alter my normal brain's physiology, though.
